Propaganda
During the time of the proposed Improvement Plan, there were many Harrisburg citizens who were not on board with the proposed changes. Vance McCormick and the Municipal League had to find ways to get those who were agianst the improvement plan, on board with the new changes. The league brought awareness to the public about the Improvement Plan through articles, ads and writings in newspapers and books, such as "A Crisis: a Brilliant Future - or a Public Failure, a Doomed City", "The Plain Truth for Plain People" and Harrisburg Must Have Filtration".
